UV-CIPP Liner for Sewage Pipe

UV CIPP (Cured-In-Place Pipe) is a state-of-the-art trenchless rehabilitation technology for in-service pipes. A flexible liner is installed into the existing pipe and cured via ultraviolet radiation, forming a robust, long-lasting new pipe structure within the original pipe. Renowned for its high efficiency, minimal on-site disruption and low environmental footprint, UV CIPP stands as a premier solution for the maintenance and restoration of aging municipal and industrial pipe infrastructure.
As a leading manufacturer of UV-CIPP（Cured-In-Place-Pipe） liners, Pro-liner specializes in trenchless pipe rehabilitation via UV-curing technology.Our R&D and production of UV-CIPP liner systems leverage high-tech processes, and we craft solutions that blend efficiency, long-lasting durability, uncompromising safety and environmental sustainability.

Core Advantages

Technical Specifications

Innovating underground rehabilitation—without a single dig.

The core materials of our UV-CIPP liners are isophthalic neopentyl glycol unsaturated polyester resin and ECR fiberglass fabric. Precisely manufactured from high-performance reinforced plastic composite materials, our liners boast exceptional mechanical and structural strength that surpasses traditional lining materials. They are universally compatible with all standard pipes ranging from DN150 to DN2400, making them a better solution for pipe rehabilitation.

Meanwhile, we provide customized solutions for non-standard pipes in engineering projects, covering round, rectangular, egg-shaped, culvert, transition and other special specifications.

Composition

01. Outer film (UV protection film)

Isolate ultraviolet rays from sunlight to prevent material curing.

02. External Fleece Layer

Prevent groundwater infiltration and protects the fiberglass layer.

03. Glass fiber impregnated with resin

The liner’s primary structural layer delivers robust acid and alkali corrosion resistance, and yields exceptional strength and toughness upon curing.

04. Inner foil

It is in direct contact with the fluid and features excellent light transmittance, facilitating the penetration of ultraviolet light.
